MATTRESS AND THE LIKE.

pplcation filed September 3, 1910. Serial No. 580,386.

To all 'whom 'it may concern:

Be it known that I, OLimR M. BURTON, a citizen of the United States, anda resident of Chicago, county of Cook, and State of Illinois, haveinvented certain new and useful Improvements in Mattresses and the Like,of which the following is a full, clear, and exact' description.

The improvement relates to mattresses, cushions and the like in which aseries of spiral springs are employed to increase the resiliency of themattress and maintain it in proper form.

The invention seeks to provide a simple and effective means by which thespring construction on the mattress can be readily and economicallyassembled and which will serve to securely but flexibly hold theindividual springs in position, so that they will maintain the propershape of the mattress or cushion and cannot cause a disagreeable gratingsound as they are compressed or expanded.

The invention consists in the features of improvement hereinafter setforth, illustrated in the preferred form in the accompanying drawingsand more particularly pointed out in the appended claims.

In the drawings, Figure 1 is a plan view of a corner of the improvedmattress or cushion. Fig. 2 is a similar view with the upper layer ofthe filling material removed and the inner covering or casing, to whichthe springs are connected, exposed. Fig. 3 is a transverse section ofthe improved mattress. Fig. 4 is a cross section of a modified form. y

The improved spring construction may be applied to mattresses orcushions of different types, but is particularly applicable to hollow orself renovating mattresses such as shown in Figs. 1 to 3 inclusive, andto box springs having upholstered tops, such as shown in Fig. 4. y

The mattress shown in Figs. 1 to 3 inclusive, comprises an outer tick orcovering 1 of suitable flexible material or fabric, an inner casing orspring covering 2, and an intermediate filling 3 of pliable material.The inner casing or covering 2 within which the spiral springs 4 arearranged is formed of stout flexible material, preferably burlap. TheSpiral springs Ltare preferably of the hour glass type and are arrangedWithin the inner casing or covering 2 in rows in the usual manner. Theend coils 5 of the spiral springs extend through the upper and lowerlayers of the inner casing or covering 2 and are secured thereto byflexible strips 6 which are woven through the end coils. The end coils5, in the preferred form of the invention, are closed and the upper andlower layers of the casing or coverin 2 are `provided with a series ofparallel s its 7 which are preferably arranged in pairs and throughwhich opposite portions of each end coil extend, as most clearly shownin Fig. 2. The flexible strips 6 extend over the outer surfaces of thecovering 2 and are woven through the portions of the end coils or rings5 which extend through the slits 7 to thereby secure the springs attheir upper and lower ends to the covering. The ends of the strips 6 arefastened to a suitable portion of the mattress and are preferablysecured to the inner covering 2 at the seam 8 (see Fig. 3), which unitesthe upper and lower layers of' the casing or covering 2 at the edge ofthe mattress. This spring construction can be economically assembled,since the closed end coils or rings 5 of the springs can be readilyinserted in the slits 7 and the strips 6 quickly Vwoven therethrough.The strips are preferably of a width nearly equal to the length of theslits 7, so that the springs are securely held in position to therebypreserve the form of the mattress and to prevent any contacting andgrating of the coils of the springs as they are compressed or expanded.-The inner casing or covering 2 to which the ends of the springs areconnected is held in positionby the quilting stitches 9 which unite itto the outer ticking and by a stitching 10 which extends through thecorners of the outer ticking and through the corners of the inner casingto formrounded upper and lower edge portions 11 of the mattress. Thefilling 3 may be of any suitable pliable material, such as cotton, hairor other suitable fiber and is preferably arranged in layers extendingaround the inner casing or spring covering 2. f

The box spring construction shown in Fig. t comprises a frame 12 of woodor other suitable material havingcross slats 13 to which the lower endsof the springs 4t are secured. The construction is provided with anupholstered top comprising an outer ticking 1, which preferably extendsaround the frame 12 and beneath v.the slats 13, an inner casing orspring covering 2 and an vinner and outer flexible coverings andintermediate filling 3. The springs l aie united to the inner covering Qin the manner already described, that is to say, the closed end coils 5extend through the slits 7 in the covering and flexible cross pieces orstrips (l and extend over the outer face of the covering and are woventhrough the endI coils. In this construction the ends of the strips 6and the edge of the covering Z extend over and are secured to a borderrod 14 and are fastened to the frame 12.

The improved construction, be economically assembled, is extremelydurable and resilient and maintains the. shape of the mattress and theindividual springs are held in proper position.

It is obvious thaty changes may be made in the details set forth withoutdeparture from the essentials of the invention as defined in the claims.

I claim as my inventioiir l. In mattresses and the like, the combinationwith an upholstered top comprising inner and outer flexible coveringsand an intermediate pliable-filling, of a series of as stated, can

spiral supporting springs having their end coils extending through saidinner covering, and flexible cross strips woven through said end coilsto secure the saine to said inner covering.

2. In mattresses and the like, the combination with an upholstered topcomprising an intermediate pliable filling, of a series of spiralsupporting springs having their end coils extending through said innercovering, and flexible strips ext-ending over the outer face of saidinner covering and woven through said end coils.

3. In mattresses and the like, the combination with an upholstered topcomprising inner andouter flexible coverings and annterrnedialiegpliable filling, of a series of spiral supporting springshaving their end coils extending through said inner covering, andflexible cross stri s woven through said end coils, the ends of saidcross strips and the edges of saidv inner covering being securedtogether and to said outer covering.

4. In a spring construction for mattresses and the like, a series ofspiral springs, a flexible covering extending over said springs andhavin slits through which the end coils of said springs extend, andflexible cross strips woven through said end coils, substantially asdescribed.

5. In a spring construction for mattresses and the like, a series ofspiral springs, a

l l l l l flexible covering extending over said springs and having slitsthrough which opposite portions of each of the end coils of said springsextend, and flexible strips extending over the outer face of saidcovering and '.Wo'ven through said end coils.

through which opposite portions of each of said end coils extend, andflexible cross strips extending over the outer surface of said covering,and Woven through said end coils.

S. In a spring construction for mattresses and the like, a series ofspiral springs having closed end coils, a fabric covering extending overof parallel slits through which opposite portions of each of 'said endcoils extend, and a series of parallel, wide, fabric strips extendingover the outer face of said cover` ing, woven through said end coils andsuitably fastened at their ends.

9. A hollow mattress comprising a series of spiral springs, an innerflexible casing or covering extending over said springs and throughwhich the upper and lower end coils of said springs extend, a series offlexible cross strips woven through said end coils to secure the same tosaid inner casing, an outer tick, a filling of pliable material betweensaid tick and said inner casing, and stitching forming upper and lowerrounded corners of the mattress and uniting said outer tick and innercasing.

10. A hollow mattress comprising an outer tick, an inner flexiblecasing, an intermediate pliable filling, a series of spiral springshaving closed end coils arranged within said inner casing, the upper andlower layers of said inner casing having slits through which said endcoils extend, and flexible strips extending over the outer surfaces ofsaid inner covering, woven through said end coils and fastened to saidinner casing at their ends.
